HandleMethod

Returns the handle of the sub expression passed to the callback

Syntax

Handle()

Remarks

This Pointer value is the argument received by a callback function associated with a function or operator defined with DefineFunction or DefineOperator. Once a uCalc.Callback object is construct with this handle, this handle typically no longer needs to be refered to directly. However, it's still avaible should you need it. uCalc interfaces with this handle underneath the hood of the uCalc.Callback object.
